Hi, I currently have a LCR of Cheap Thrills speakers from diysoundgroup that Bill Waslo designed (here's the original design thread: http://www.hificircuit.com/community...12-dna360.197/
) which are awesome but I'm looking to upgrade. I have a few ideas on what I want to do, but not sure what to do, lol.
My goals are something bigger with better pattern control lower and would really like something with sensitivity of 100/db watt or more. I'm currently looking at Titan 615lx, 1899s and also considering diy'ing some kind of JBL 4722 variant. I'm in Canada so I get screwed on driver prices a little and I enjoy woodworking, so I'm not afraid to build my own enclosures etc. At first I thought I would just get the Titans and enjoy, but I don't want to get the nagging feeling in the back of my mind that I should have went for something more crazy. I currently have 6 B&C 21SW152s and 1 Celestion NTR21-5010JD for subs. I'm still working on an enclosure design for the 21sw152s....going fairly large ported or using passive radiators after I try them out. Planning on tuning around ~17hz.
I like the idea of building a proven design since I know it will sound great but I'm also curious about trying to put something together myself and thought a diy JBL 4722 would be a nice way to ease into going a little off the beaten path. My idea for the DIY JBL 4722 involves using the 2384 horn mated to the 2453H-SL compression driver (thanks for doing all the legwork there and measurements
) and then finding some 15s to work under the HF section. I have found some NEO B&C drivers that appear to be OEM'ed for Yorkville (model 15/219-8) that Long and McQuade are clearing out that model similarly to the JBL 265 drivers in the 4722. Here are their TS parameters:
Vas: 199.24 l
PE: 400w RMS
They are a little more sensitive than the 265s but have less xmax and they are also less than half the price ($99 CDN) which adds up quick when you need to buy 6 drivers. I would think I would tune a 8cuft enclosure to 50hz or so with the two of the drivers per cab. My other idea is to turn the 4722 into an MTM with one 15 over and under the horn. Wouldn't that work better than the current 4722 implementation and might be a better configuration for smaller theatres that don't need the horn up so high? I have a couple Crown DSI amps so I could go active technically, but I was wondering how well the stock 4722 crossover would work.
Also, wondering if there is something else coming up in the DIYSOUNDGROUP skunkworks that would be up my alley. A MTM Titan would be awesome, hint hint :P
Any suggestions? Thanks in advance
